SPECIFICATION forming part of. Letters Patent No. 351,566, dated October 26, 1886.

' Application filed December 2, 1885, Serial N 0. 184,440. No model.)

To all whom it may concern:

Be it known that I, ALBERT BALL, of Claremont, in the county of Sullivan and State of New Hampshire, have invented a new and Im-' proved Rock-Boring Machine; andI do hereby declare that the following is a full and exact description of the. same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention relates particularly to a drilling-machine for boring deep holes, and is especially used for underground prospecting in 7 connection with a diamond-armed head and where it is convenient to have the drill mount- 7 I 5 ed on a light frame and not require much space in its operation.

My object is to provide a drill which shall be very light, require small room, be very easily worked, be very steady and very economicalin its working, which can be at any angle from horizontal to perpendicular. The use of two parallel standards is not novel, nor is the hanging upon such standards of a drilling-machine which can be turned in different directions; but one novelty of my invention consists in the position and manner of setting my machine upon such standards, between them, so as to have the weight and strain directly upon and against both standards, instead of at one side of them, while at the same time the drill can be swung on trunnions in aplane almost at right angles with the plane of the standards. These planes could be at right angles; but I prefer to have them not quite rectangu- 3 5 lar, so as to allow of the engine-shaft not interfering with the standards.

Other novelties of my invention consist in the manner of securing my machine to the standards; in the devices for swiveling the drill without at the same time disturbing the engine and its shaft; in the combination with a special single-trunk engine; in the device for raising and lowering themachine as necessary in the process of drilling to remove and change, rods; and in the combination, with these devices, of my improved friction-clutch for feeding. the drill and my device for rapid adjustment of my machine for withdrawing the rods.

The novelties in my machine-standards and method of bracing the same are covered by an independent application filed of even date herewith.

For a better understanding of my improvementsin detail, attention is invited to the accompanying drawings, wherein- Figure 1 shows my machine mounted on its 7 standards. Fig. 2 is a top view of the same.

Fig. 3 is an enlarged sectional view of part of the machine, including the feed mechanism. Fig. 4 is an end view of the same; and Fig. 5 is a top View of the same, with some of the parts removed, showing the mechanism for swiveling the machine and for clamping it to the standards. 6 5

Similar letters of reference indicate corresponding parts.

A A represent the standards whereon the machine generally is supported when in use,

although for some work other supports could be. used. I

B B, Figs. 1' and 2, are the stretchers which stiffen the standards and 'keep them parallel.

C (3 C 0*, Figs. 1, 2, and 5, are clamps which hold the machine to the standards.

D D, Figs. 1 and 2, are the brace-clamps. j, Figs. 1 and 2, is one of the braces. For a detailed description of these braces and braceclamps I would refer to an application for Lot ters Patent for same intended to be filed simultaneously herewith.

E E, Figs. 1, 2, and 3, are boxes for the driving-quill. F, Figs. 1, 2, 3, and etfis the driving-quill which carries the spindle.

G, Figs. 1 and 2, is the balance-wheel.

H, Figs. 1, 2, and 3, is one ofthe feed-gears, and is held by friction-clutch H H, Figs. 1 and 3, is the gear which drives c the gear H.

The friction-clutch H is mounted on one end of the feed-shaft T, whose gear H is held between two disks or plates, h h, which should be made of some material that will not cut or wear metal to any extent.

H is a stationary collar splined to the feedshaft T, between its outer bearing, E, and the gear H, and H is a movable collar splined to this same shaft on the other side of the gear H. This lastnamed collar has a tubular hub, h, within which is a spiral spring, h encircling the end of the shaft T. This spring has bearing at its inner end against a shoulder, If, at the base of the hub I and has bearing at its outer end against an adjusting-nut, V. This nut screws upon the shaft T, and its base is of a di ameter to nicely fit the bore of the hub 11/. By means of this nut the spring is compressed against the shoulder h and the collar H, together with the adjoining disk or plate h, at any desired pressure. This pressure is to be regulated by the nut V, and the gear H is thereby held more or less firmly between the disks or plates h h to revolve with the shaft T. If the resist ance to the quill F and spindle N be less than the friction or pressure applied by the disks or plates h h to the gear H, they will then work readily through the medium of the gears H and H 5 but if the resistance equals or exceeds said friction or pressure: the gear H will slip more or less between the disks h 71, and independent, to that extent, of its shaft.

I, Fig. 1, is the engine-frame which holds the, cylinder and crank.

KKK,Figs. 1 and 2,is a cap of engine-frame, preferably made in a single piece. It also forms a part of the bearings for the crank-shaft.

L, Figs. 1 and 2, isabevel-gear, which is on crank-shaft, and which drives the gear, L, Figs. 1, 2, and 3, the said bevel-gear L being on the quill which drives the drill.

M, Figs. 1, 2, and 5, is the plate carrying the trunnion f, Fig. 5, to which one side of the spindle frame is attached and on which it swivels. The other trunnion is formed by the end of the engine-box, as shown by the dottedline M, Fig. 1, at the opening indicated by X, Fig. 5.

N, Figs. 1, 2, 3, and 4, is the screw-spindle which carries the drill.

O 0,.Figs. 2 and 8, are friction-plates carrying friction balls or rollers.

P is the guard that holds the friction-balls in place.

Q, Fig. 1, is a hand-wheel with extended hub fastened to a box (which is preferably placed for convenience) 011 the lower stretcher of the standards. It is threaded inside, and carries a hollow screw, R, with a rod, m. Their function is to lower the machine when it is desired to remove the drill-rods from the hole being bored, and after the rods have been replaced in the hole to raise again the machine to its proper place for working the rods.

S, Figs. 2, 3, and 4, is the nut-gear threaded to fit the spindle, and which feeds it forward and draws it back, and S is the gear on feed shaft T, which drives the nut-gear S.

U is a latch, which holds the feed-shaft in position while the drill is fed forward. The latch is then as shown in Fig. 3. When the drill is to be drawn back, the latch is raised up and the shaft slipped back and the gears H and H disengaged and the collar i brought on the other side of the latch.

U is a spiral spring holding in place the latch U.

WV, Fig. 3, is astop-lever mounted on abracket, W, by a bolt, c. There isa pin, 1), Fig. 3, in the nut-gear S, which, when the stop-lever is thrown into position, comes into contact with the lever and prevents the nut-gear from revolving and holds it, but is not so rigid but what ifany obstacle is encountered it will yield sufficiently to allow the nutgear to revolve with the spindle. In drilling, this lever is thrown back out of position, but when it is desired to draw up the drill, the feed-shaft T is thrown back until H and Hare out of gear, the lever is thrown forward, and the nut-gear, being held from revolvingwhile the spindle is being revolved by its drivinggear, the spindle is rapidly drawn up.

0, Fig. 1, is a shoe held by bolts 0'. The heads of these bolts c,when screwed up, pinch the plate 0 and prevent its turning. These bolts pass through the shoe 0 and hold it in place, even when they and the set-screw are loosened.

I, Fig. 1, is a set-screw, whose object is to force the shoe 0 against the plate 6.

0, Figs. 1, 2, 4, and 5, is a plate turned concentric with the trunnion f, and n is a cap for same.

In mounting the machine on standards, I use a number of special clamps, GOWPC", Figs. 1, 2, and 5. Instead of these, there could be used clamps similar to those I use on the braces, (and for which I intend to apply for Letters Patent simultaneously herewith,) but for 01)- vious reasons it is desirable to have a swing bolt.

9, Figs. 1, 2, and 5, shows the bolt, and g the slot in which the bolt swings on the pin 1.

t i is the link (secured at each end by a pin) which holds the other end of the clamp c. In

mounting the machine I prefer to use four of I10 these clamps, as follows: C is attached to the engine-frame and top head, onehalf of the clamp being cast as a part of the frame and head. Parts of G and C are cast tothe bottom head of the steam-cylinder as a part thereof,

and extending across (at either end of the arm k) from one standard to the other, thereby making a very stiff support for the machine. Part of C (clearly shown in Fig. 5) is cast as a part of the plate M and trunnion f, on which one side of the spindle-frame is swung.

0, Figs. 1 and 2, is crank-shaft.

d d d d are set-screws to hold the stretchers B to the standards in position.

1' r 1' r are screws for adjusting and holding the standards.

12111) is the spindle-frame, preferably in one piece and forming both the plates 6 and s, which are turned concentric.

In the practical working of the drill I place one of the brace-clamps D so that the plate M will come into contact with it on the standard when the drill is at work,and the lower brace clamp D so that the plate M shall rest against it when the machine is lowered sufficiently to be out of the way of the drillr ods when it is through the spindle, and I thereby avoid the use of clutches and weight and expense, large journals on the driving-quill, and accompanying friction. To swivel the drill to the desired angle, it is only necessary to loosen the nuts upon the bolts 0 and the set-screw Z, thereby freeing the plate 6 from the friction-shoe c. When the drill is adjusted, the set-screw is tightenedand the shoe forced against the plate 0, and the bolts 0 are tightened. The

bevel-gears L and L are'so arranged that in swiveling the drill L remains stationary,while L turns upon L.
